[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown, an embodiment of the present invention provides a solid material quantitative discharging device, comprising a frame 1, wherein evenly distributed material barrels 2 are fixed inside the frame 1, a discharging mechanism 3 is provided at the bottom of each material barrel 2, a valve assembly is provided at the material outlet of the discharging mechanism 3, and a weighing assembly is provided at the bottom of the discharging mechanism 3;

[0022] The discharging mechanism 3 includes a discharging pipe 4 fixedly connected to the bottom of the barrel 2, and a feeding screw 5 is rotatably connected inside the discharging pipe 4. A stepper motor 6 is provided at one end of the discharging pipe 4, and the output end of the stepper motor 6 is fixed to the feeding screw 5 through a quick-release coupling 15. A dynamic sealing assembly 16 is fixed to the end of the discharging pipe 4 close to the stepper motor 6.

[0023] Specifically, in this embodiment, a frame 1 is included, and evenly distributed material barrels 2 are fixed inside the frame 1. The number of the material barrels 2 is preferably 3-10. The material barrels 2 are filled with solid particles. When the material barrels 2 are filled with milk tea ingredients, and the types of milk tea ingredients contained in each material barrel 2 are different, a discharging mechanism 3 is provided at the bottom of each material barrel 2. The discharging mechanism 3 is used to discharge solid particles. A valve assembly is provided at the material outlet of the discharging mechanism 3. The valve assembly is used to close the material outlet of the discharging mechanism 3. A weighing assembly is provided at the bottom of the discharging mechanism 3. The weighing assembly is used to weigh the solid material in the material barrel 2.

[0024] The discharging mechanism 3 includes a discharging pipe 4 fixedly connected to the bottom of the barrel 2. The discharging pipe 4 is connected to the barrel 2, and the barrel 2 and the discharging pipe 4 are integrally formed. The internal rotation of the discharging pipe 4 is connected to the feeding screw 5. A stepper motor 6 is provided at one end of the discharging pipe 4. The output end of the stepper motor 6 is fixed to the feeding screw 5 by a quick-release coupling 15. The quick-release coupling 15 is a prior art. When the stepper motor 6 rotates, it can drive the feeding screw 5 to rotate, and the quick-release coupling 15 can quickly disengage the stepper motor 6 and the feeding screw 5. A dynamic sealing assembly 16 is fixed to the end of the discharging pipe 4 close to the stepper motor 6. The dynamic sealing assembly 16 is used to seal the end of the discharging pipe 4 close to the stepper motor 6 to prevent solid material from spilling from there. The number of revolutions of the stepper motor 6 each time is controlled by the upper computer, so that each time the stepper motor 6 works, it stops after rotating to a preset number of revolutions.

[0025] The present invention provides a solid material quantitative feeding device, which rotates a stepper motor 6 a predetermined number of times, so that the stepper motor 6 can drive the feeding screw 5 to quantitatively discharge the solid material inside the barrel 2. When multiple solid materials are fed, there is no need for frequent manual digging, which makes the quantitative feeding of multiple solid materials more convenient and accurate, and is less prone to errors than manual feeding.

[0026] In another embodiment provided by the present invention, a support plate 7 is provided at the bottom of the discharge pipe 4, and a quick-release assembly 9 is fixed to the top outer wall of the support plate 7. The quick-release assembly 9 is a prior art, and there are at least two of them. The discharge pipe 4 is fixed to the support plate 7 through the quick-release assembly 9, so that the discharge pipe 4 can be quickly installed, fixed and disassembled on the support plate 7 through the quick-release assembly 9, and the support plate 7 is fixed to the stepper motor 6.

[0027] In another embodiment provided by the present invention, the valve assembly includes a piston cylinder 10 connected to one end of the discharge pipe 4, the piston cylinder 10 is fixed to the discharge pipe 4, and the interior of the piston cylinder 10 is connected to the discharge pipe 4, a piston column 11 is inserted into the interior of the piston cylinder 10, and the friction between the piston column 11 and the piston cylinder 10 is small. A cylinder 12 fixed to the frame 1 is provided on the top of the piston column 11, and a quick-release connector 14 is fixed to the output shaft of the cylinder 12. The bottom of the quick-release connector 14 is fixed to the piston cylinder 11, and the cylinder 12 is provided with a quick-release connector 14. 12 drives the piston column 11 to move inside the piston cylinder 10, so that the piston cylinder 10 and the discharge pipe 4 can be closed, and then the piston column 11 can push out the material attached to the inner wall of the piston cylinder 10 and close the discharge pipe 4 to prevent the material from spilling from the discharge pipe 4. The quick-release connector 14 is an existing technology. The piston cylinder 10 can also be easily disassembled from the cylinder 12 through the quick-release connector 14, making it more convenient to clean the barrel 2 and the inside of the piston cylinder 10.

[0028] In another embodiment provided by the present invention, the weighing assembly includes a weighing sensor 8 fixed to the bottom of the support plate 7, and a connecting seat 13 is fixed to the bottom of the weighing sensor 8, and the connecting seat 13 is fixed to the frame 1. The weighing sensor 8 transmits the measured weight to the host computer through an electrical signal. After the solid material is discharged, the host computer calculates the total weight detected according to the electrical signal of the weighing sensor 8. When the total weight is lower than the set value, the material inside the barrel 2 is missing. At this time, the host computer can limit the stepping motor 6 from working to prevent the phenomenon of insufficient discharge of solid material, so that it is not easy to have insufficient ingredients when brewing milk tea.

[0029] In another embodiment provided by the present invention, a refrigerator 17 is fixed inside the frame 1, and the discharging mechanism 3 is located inside the refrigerator 17. The interior of the refrigerator 17 has a refrigeration mechanism of the prior art, so that the milk tea ingredients in the material barrel 2 can be refrigerated, thereby preventing the milk tea ingredients from deteriorating due to high temperature; a cup discharging mechanism 18 is provided inside the frame 1, and the cup discharging mechanism 18 is located on one side of the discharging mechanism 3. The cup discharging mechanism 18 is also of the prior art. The cup discharging mechanism 18 is used to temporarily store milk tea cups, making it more convenient for staff to take milk tea cups.

[0030] Working principle: When it is necessary to quantitatively discharge solid materials, first remove the material cup through the cup discharge mechanism 18, and then place the material cup under the piston cylinder 10, and drive the piston rod 11 upward through the cylinder 12, so that the bottom outlet of the piston cylinder 10 is connected to the discharge pipe 4, and then the stepper motor 6 rotates a predetermined number of circles, so that the stepper motor 6 drives the feeding screw 5 to rotate, and the feeding screw 5 quantitatively transports the solid material inside the barrel 2, thereby causing the solid material to flow from the bottom of the piston cylinder 10 into the material cup. When the stepper motor 6 stops rotating, the piston rod 11 is driven downward by the cylinder 12, so that the piston rod 11 closes the piston cylinder 10 and the discharge pipe 4 to prevent the solid particulate material inside the discharge pipe 4 from flowing out; each stepper motor 6 can be pre-set to rotate a different number of circles, and different solid materials can be respectively contained in multiple barrels 2, so that each material can be quantitatively discharged according to its own set weight, so that different solid materials can be conveniently quantitatively proportioned in the material cup.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
